Medium Volume Saw

CUTTING TRIALS

All specimens detailed were cut in 11 hours on Sharp And Tappin`s latest generation CPS 1000 composite plate saw, with all specimens being found to be within ±0.05mm of the set dimensions with side to side parallelism of better than 0.05mm and edge finishes that were suitable to test without any additional preparation. All specimens were machined from 600mm x 600mm flat laminates.

Summary

All Specimens were machined and found to within the required tolerances for all ASTM or ISO standards that the specimens would be prepared i.a.w. Using Mark 1 Sharp and Tappin Composite Plate saw including post preparation of specimens would take ~2-4mins per specimen. Using manual saw such as a modified tile cutter or similar including setting time, post preparation of specimens etc would take >5mins per specimen - this does not include allowances for additional specimens due to inevitable scrapping of specimens for being out of tolerance.
